Subwoofer:

In this menu point you set whether a subwoofer is present in your loudspeaker system. Select one of the following settings:

Bassmanager recommended setting for sub- woofer / satellite systems.

If a sub-woofer is present. The signals of the bass effect channel (LFE), and all other low frequency bass signals (below the set transition frequency) which are not reproduced by the full-range loudspeakers, are passed to the sub-woofer channel. In this mode it may occur that the sub-woofer has no signal to reproduce in some surround modes or with multi-channel input signals which lack an LFE channel.

If the bass manager is in use, the low-pass filter on the sub-woofer should be switched off, as the bass manager carries out the filtering.

Permanent recommended setting for full-range loudspeakers and sub-woofer.

If a sub-woofer is present and you wish it to operate constantly. In addition to bass management the signals of all channels are mixed together and reproduced by the sub- woofer.

For constant sub-woofer operation the low- pass filter on the sub-woofer must be switched on and the transition frequency on the sub- woofer set in such a way that the sub-woofer only reproduces signals below the bottom transition frequency of the main loudspeakers (generally 30 - 40 Hz).

none if this setting is selected, at least the main loudspeakers must be full-range types.

If no sub-woofer is present. The signals of the bass effect channel (LFE) and all other low frequency bass signals (below the set transition frequency) are reproduced by the main loudspeakers.

Note:

Provided that you have switched on the subwoofer in the 'Speaker Setup', then you can adjust its level in the 'Main Menu' within the range -10 (dB) to +10 (dB), so that the volume of the subwoofer matches the volume of the other channels.

Satellitehighpass:

Here the lower transition frequency for satellite speakers can be selected. The bass range below the frequency set here (for all loudspeakers whose size is set as 'Satellite') is mixed by the bass manager onto other suitable loudspeakers and the sub-woofer.

The following values (Hz) can be set:

50 60 70 80 90 100 120 150 180
